RK4SpringDescription class

Spring parameters for the RK4 simulation.

tension maps to stiffness. friction maps to damping. Fuchsia always used friction=50 and varied tension:

• 250 (theatrical/slow)
• 450 (default)
• 600 (responsive)
• 750 (snappy)
• 900 (snappiest)

Constructors

RK4SpringDescription({double tension = 450.0, double friction = 50.0})

const

RK4SpringDescription.fromSpring(SpringDescription sd)

Create from Flutter's SpringDescription. Maps stiffness→tension, damping→friction. Mass is ignored (Fuchsia always used mass=1).
